Add Docker binary and builds plugin to build container image for new default task

[coderabbitai]

Context

After PR #1357, the default task has been changed to docker-images:package, which requires the docker binary and the builds plugin to be available in the build environment.

Problem

For users who build inside containers, these dependencies may not be available. We need to either:

• Create a new build container image with Docker support, or
• Add Docker to the existing clp-core-dependencies-x86-ubuntu-jammy image
